Abstract Concerning the stamping and jointing techniques of stainless steel impeller,a shaping method of centrifugal pump impeller is presented based on the structure characteristic of centrifugal pump,which introduces shrouds with taper and twist blade.Laser welding is used to joint the blades and the shrouds which tackles the distortion of hub according to the mechanical performance of the material.By avoiding the bunch flow phenomena in the impllers,the shroud and hub can ensure no-distortion,which improves the hydrodynamic performance effectively.centrifugal pump;stamping;impeller;shaping technology
